Description
Soil erosion can cause a progressive degradation of hillslopes, especially in steep-slope agricultural landscapes. In this study, the formation of spatial erosion patterns was evaluated in three typical steep-slope vineyard cultivation practices in northern Italy: dry-stone wall terraces, earth bank terraces and vertical cultivation (Italian: rittochino). UAV surveys in three vineyards provided high-resolution data on topography and land use serving as input for two GIS-based erosion models: the Revised Universal Soil Loss Equation (RUSLE) and SIMulated Water Erosion model (SIMWE). Annual RUSLE simulations showed how the two terracing practices (i.e. dry-stone walls and earth banks) effectively safeguarded large areas from soil loss, whereas the non-terraced vertical cultivation produced widely distributed soil loss with increasing severity according to slope length and steepness. In intense single-event conditions …
